This invention relates to heating and drying apparatus using hot air and more particularly to apparatus for individually drying the hair after washing or other wetting 4 5 for beauty culture purposes.

The general purpose of the invention is to provide a hood for a hot air drying apparatus adapted to fit about the hair and being pervious to air so that the warm air forced down about the head will pass out'through the hood near the hair in all directions.

It is also an object of the invention to provide replaceable, sanitary hoods so that each person using a hair dryer will have an individual hoo d.

The above and other objects of the invention are achieved by the apparatus illustrated and described below, it being understood that the inventionis not limited to the exact details thereof shown and described. This application is a division of application Serial No. 451,486, filed-May 10,1930.

In the drawing,

Figure 1 is an enlarged sectional view of a hood embodying the invention shown applied to the hea Figure 2 is an enlarged detailed view of a portion of Figure 1;

Figure 3 is a detail section through the sanitary napkin hood member; and

Figure 4 is a plan view of the unfolded sanitary napkin hood incorporated in the invention.

Referring to Figure 1 of the drawing, there is shown therein the lower ortion 36 of a telescopic pipe through. whic is delivered heated air for hair d purposes. According to the original s i cation, the pipe 36 may be one of a p urality of such pipes, and they may be connected to a common device for heating the air.

Secured to the bottom of the telescoping.

pipe 36 is a flexible hood member 43 of airti ht material to the bottom of which is fixed vio us to air such as cloth felted fibrous matenal or porous paper and is normally furnlshed in flat form as illustrated in Figure Cords 47 may be provided on the hood member 46 which may be tied behind the users neck, the lower portion of the hood be- 1ng athered under the strings to secure the hoo 1 snugly about the head as seen in Figure A fresh, clean, sanitary hood member 46 is folded into hood shape and removably secured to the flexible, airtight hoodmember 43- through the agency of the cooperating hoops 44 and 45. The ends of the hood'member 46 may be merely overlapped and held by the hoops. However,clips, pins or sna s are preferably used to assist in holding e hood member in shape at points remote from the hoops. The length of the telescoping pipe 36 is adjusted so that the hood 43 is brought down into relation with the head to be dried as illustrated in Figure 1. The cords 47 are tied behind the user s neck which draw the removable hood member snugly about the head. The flexibility of the airtight hood member 43 allows the user considerable freedom of head movement. Hot air may now be delivered to the hoods as de- 80 scribed in the original application.

After one person has dried her hair the hood member 46 used by her is removed and discarded or sent to-be cleaned, and a fresh one is clamped on the flexible hood 43 in its place by the hoops 44 and 45.

As many changes could be made in the construction disclosed it is intended that all matter contained in the above descri tion or illustrated in the accompanying win' shall be interpreted as illustrative only an not in a limiting sense. Accordingly, various modifications and applications of the invention can be resorted to without departing from the spirit of the invention or the scope of the appended claims.

What is claimed is: v

1. In combination, a flexible, air-tight hood member, means for supplying hot air to said hoodmember and a sanitary, air-pervious hood member removably held at the bottom of said first hood member to fit about a users head whereby the hair will be dried by the flow of hot air into and through said secondnamed hood member.

I 2. In combination, an air-tight hood member, means for supplying hot air to said hood member and a sanltary, airervious hood member removably held at the ttom of said first hood member to fit about a users head 1 wlereby the hair will be dried by the flow of hot air into and through said secondnamed hood member.

3. Apparatus for drying hair comprising a eoliduit for supplying hot air, a hood mem- 15 her of flexible, relative y impervious material connected thereto and to which the air is delivered, and a hood member of flexible, pervious material at the lower portion of the hood to 'fit about a persons' head where- 2 by heated air is conveyed to the hair by the impervious hood and passed through the hair and out through the pervious hood in all directions about the head.

a 4. Apparatus for drying hair includin ,a hood member of air-pervious material adapted to be fitted about the head, and means for supplying heated air to the interior of the hood so as to pass through the hair and out through the hood in all direc- .tions.
